摘要:
A color photographic recording material containing a coupler which releases a photographically active compound.Couplers corresponding to formula (I) couple with color developers to form yellow to yellow-orange dyes and, in doing so, release the residue X as a photographically active compounds. Where X is a development inhibitor, remarkably high inter-image and edge effects can be obtained. ##STR1## in which R.sup.1 represents alkyl, a heterocyclic or carbocyclic aromatic group or -NH-CO-R.sup.2 ;R.sup.2 represents alkyl, aryl or -NH-R.sup.3 ;R.sup.3 represents alkyl or aryl;Q represents the groups to complete a fused, optionally substituted benzene or heterocyclic ring;X represents the residue of a photographically active compound;TIME represents a bond which, on reaction of the coupler with the oxidation product of a color developer, is released together with the residue X attached thereto and, in turn, releases the residue X as a photographically active compound under the development conditions;n=0 or 1.
